I just tried your DSDT, I did encounter a couple odd issues. When using a HDMI cable my monitor would go to sleep before It reaches the login screen. When I switched to DVI to HDMI , monitor was detected , I switched back to HDMI and so far monitor does not go to sleep anymore.

Now I went to see if HDMI audio was working and unfortunately I only see Apple TV Airplay as an option under system settings/ sound . Going to try disconnecting from the network and see if that helps.

Great .

Looks like you did not install the Audio kext from multibeast. Along with the HDMI, other Audio outputs should have been visible in the screenshot.
But i know HDMI Audio works OOB using DSDT Audio edits 01 or 03. I don't install Audio kext from multibest as well, coz HDMI is the only output i use and it works OOB for me.

Hello guys.
I started this thread but havent repsonded for a long.
I had my mountain lion installed and all working fine exept the 5.1 sound that didnt find a solution.And the buggy usb 3.0 ports.
I did some tests with my windows installs and now i cant boot in my osx drive.I tried a lot of times but nothing.
So i decided to do a clean install.
My motherboard is Asrock z68 pro3 gen3.
Cpu: 2500k oc at 4.2Ghz.
HDD: ocz ssd 60gb
GPU: ATI 5850 1GB.
I used unibeast from VMware mountain lion to fix a usb mountain lion install.
I just install mountain lion 10.8.2 now.
So i want to ask.In the multibeast as i show from previous post:
1)i ll check user dsdt and i ll use MiniITX dsdt,right?
2)i ll check audio and lan driver.
3)1080p
Anything else i need to check from the start?
Ty for ur asnwers!
